ADA4077-2 4 MHZ, 7 NV/√HZ, low offset and drift, high-precision amplifier
The ADA4077-2 is a two-channel amplifier with very low offset voltage, low drift, low input bias current, noise, and power consumption. Stable output with capacitive loads above 1000 pF without external compensation.
Applications for this amplifier include sensor signal conditioning (e.g., thermocouples, RTDs, strain gauges), process control front-end amplifiers, and precision diode power measurement in optical and wireless transmission systems. ADA4077-2 is suitable for line-powered portable instrumentation, precision filters, and voltage or current measurement and level setting.
Unlike other competing amplifiers, the ADA4077-2 is rated for an extended industrial temperature range of −40°C to +125°C, and the MSL1 is rated for the most demanding operating environments. The device is available in 8-pin SOIC (Class B included) and MSOP (Class A only) packages.
